JOHN ROY, OF NEW ORLEANS, LOUISIANA.

FILE-DRIVER.

SPECIFICATION forming part of Letters Patent No. 278,603, dated May 29, 1883. i Application filed December 18,1882. (No model.)

To all whom it may concern Be it known that I, JOHNROY, a resident parish of Orleans,

and State of Louisiana, have invented a certain new and useful Improvement inPile- Drivers and I do hereby declare the following to be a full, clear, and correct description .of the same, reference drawings, making a part of this specification.

This invention relates to certain improvements in pile-driving machines; and it consists in a combination, with the main frame thereof, of a tramway and movable leads, whereby all the piles in a bent can be driven perpendicularlyor at an angle without moving the maehine. r

My invention further consists in the combi' I nation of parts and the details of construction,

hereinafter more fully described and specifically claimed. I

In the accompanyingdrawings, Figure 1 represents a front elevation of my machine, and Fig. 2 a side view of same.

The letterA designates longitudinal timbers,- secured at requisite distances apart by having cross-timbers B bolted or otherwise secured thereto, so as to constitnte the lower part of the machine. The timbersA are preferably arranged in pairs and mounted on wheels 0, so

as to enable the same to he moved in a forward or backward direction; Sectional frames are erected at and near the forward end of the timbers A, as shown at D E. These sections are properly strengthened by means of braces, and are connected at their upper ends by longitudinal side timbers, F, from which the diagonal braces extend downwardly and rearwardly, as shown at G H. The frame is'furthermore strengthened by chains or rods t t, which extend fore and aft from the upper part of the sectional frame E to the outer corners of the lower frame, as shown.

Across" the forward ends of hers, F, is constructed a tramway or pair of rails, K K, on which operates a pair of wheels, ll, that are fitted so as to revolve with an axle, or on pins m m connected with a block, N, forming the head of the leads 0, the sides of which. are secured at requisite distances apart by braces a andan adjustable box, I), the latter connected to the leads by bolts, and

being bad to the annexed the upper tim to the lower front timber, B, by bolts, stirrups, or other means which will admit of thesame being quickly released whenever it is required to more the leads to the right or left of the frame. The leads are moved in either of the aforesaid directions by means of ropes or chainsp p, which are connected with the opposite ends of the head-block N, and which pass over sheaves q q at the ends of the tramway, from whence they pass downwardly to windlasses R R in the lower part of the front sectional frame, as shown.

The boiler and operating machinery is mounted in the rear end of the lower part of the frame, thus serving to properly balance and hold the frame in position.

An attachment for sawing and trimming the piles is also connected with my machine; but as this part may form the subject of another application no further reference is herein made to the same; nor is it deemed necessary to particularly refer to the hoisting mechanism shown, as said mechanism is common in all pile-driving machines. i

From the above description it will be seen that the leads can be moved to the right or 'left or held in a diagonal position, as the nature of the work may require. p.

Having described my invention, what I claim as new, and desire to secure by Letters Patent,

1. The combination, in a pile-driver having a frame provided at its top with a tram way, of the adjustable leads suspended from a wheelaxle or pivots, so that the piles may be driven perpendicularly or at an angle, as described.

2. In pile-driving machines, a frame composed of timbers A and B, having vertical sectional frame D and E, secured thereto, as described, and the said frames surmounted by a tramway, K, in combination with the movable leads 0, devices for securing them to the frame '13, and operating mechanism, substantially as and for the purpose specified.

In testimony whereof'I affix my signature in presence of two witnesses.

JOHN nor.
